摘要：
Parametric excitation of the resonance oscillations of dust particles in a near-electrode layer of an RF discharge with low-frequency-modulated amplitude of the discharge voltage gas been studied. Depending on the modulation depth, both the dynamic stabilization of particles (leading to a change in the structure of dusty medium) and the parametric resonance in a certain band of excitation frequencies are possible. A model for the observed phenomenon is proposed. It is shown that the excitation of oscillations of dust particles has a threshold character.
